Settings and such...

Jake,

We are just now getting to the GYRO. I am not sure if you've seen this link from the Killer Bees Team but this is where we are starting for our Gyro primer.

After this weekend I should be able to let you know more once we get the gyro up and running. Also, the GYRO from last years KOP had a faster response in terms of measuring DPS (Degrees Per Second). Could measurement lag be causing your measurement anomaly?

Please let us know how it works out, and if you wouldn't mind sharing your Gyro code we would like to see it.
